[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0038] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] See also Figure 1 and Figure 8The immersive virtual reality system for the magnetic resonance system provided by the present application is now described. The magnetic resonance system includes a magnet cavity 20, and the immersive virtual reality system includes a Faraday cage 1 and a virtual reality presentation component 2. The Faraday cage 1 is arranged in the magnet cavity 20 and away from the magnetic field center of the magnet cavity 20. The magnetic field center of the magnetic cavity refers to the center of the scanning imaging of the magnetic resonance system.

[0041] The virtual reality presentation component 2 includes a display element 21 and an optical path transmission element 22. The display element 21 is located inside the Faraday cage 1, and the optical path transmission element 22 is at least partially located outside the Faraday cage 1. The display element 21 is used to provide a virtual visual scene, and the optical path transmission element 22 is used to transmit the virtual visual scene of the display element 21 along a set transmission optical path. In practical applications, the transmission along the set transmission optical path can be transmitted to the eyes of the detection object. In this way, when the detection object is subjected to magnetic resonance scanning imaging, the detection object can watch the virtual visual scene of the display element 21. Based on this, on the one hand, the immersive experience of the detection object can be improved, the claustrophobia of the detection object can be reduced, the anxiety of the detection object can be reduced, and the success rate of magnetic resonance scanning can be improved; on the other hand, different virtual visual scenes can be provided by the display element 21 to provide different visual stimulations to the detection object, and brain health and brain science research can be carried out according to the detection object's response to different virtual visual scenes.

[0042] Since the optical path transmission component 22 only includes optical components and no electrical components, and optical components are generally magneto-electrically compatible, the optical path transmission component 22 will not be affected by the magnetic field and radio frequency in the magnet cavity 20. There is no need to place the optical path transmission component 22 in the Faraday cage 1. The optical path transmission component 22 is at least partially located outside the Faraday cage 1, that is, the optical path transmission component 22 can be completely located outside the Faraday cage 1 or partially located outside the Faraday cage 1, which can reduce the volume of the Faraday cage 1.

[0043] A Faraday cage 1 is a cage made of metal or a good conductor that has the following functions:

[0044] ① Shielding external magnetic field: Faraday cage 1 can shield the influence of external magnetic field. When Faraday cage 1 is placed in an external magnetic field, the free electrons inside Faraday cage 1 will be affected by the force of the magnetic field, thereby generating current. The magnetic field generated by this current will interact with the external magnetic field, offset the influence of the external magnetic field, and achieve the effect of magnetic field shielding.

[0045] ② High-frequency electromagnetic wave absorption: The Faraday cage 1 has an absorption effect on high-frequency electromagnetic waves. When high-frequency electromagnetic waves are injected into the Faraday cage 1, the charges inside the conductor will be moved by the high-frequency electromagnetic waves, thereby absorbing the energy of the electromagnetic waves and preventing them from leaking out.

[0046] ③ Protect internal electronic equipment: Faraday cage 1 can be used to protect electronic equipment inside Faraday cage 1 from external electromagnetic interference. In places with complex electromagnetic environments, such as laboratories, medical equipment and other places, the use of Faraday cage 1 can effectively reduce the impact of external electromagnetic interference on the equipment and ensure the normal operation of the equipment.

[0047] Compared with the prior art, the immersive virtual reality system for a magnetic resonance system provided by the present application locates a display element 21 in a Faraday cage 1, and the Faraday cage 1 is disposed in a magnet cavity 20. The Faraday cage 1 can protect the display element 21 from the influence of the magnetic field and radio frequency interference in the magnet cavity 20, which can not only ensure that the display element 21 displays normally in the magnet cavity 20, but also prevent the display element 21 from causing changes in magnetic resonance imaging in the magnet cavity 20, thereby improving the effectiveness and efficiency of the use of magnetic resonance images.

[0048] In one embodiment, the immersive virtual reality system further includes a tracking component located in the Faraday cage 1, and the tracking component is used to perform eye tracking or head tracking of the detection object.

[0049] The purposes of eye tracking or head tracking during MRI scans are as follows:

[0050] ① Maintain stability: Eye tracking or head tracking can help ensure that the head and eye position of the subject remain stable during the MRI scan. This is very important for obtaining clear MRI images, because any movement of the subject's head or eyes may cause the MRI image to be blurred or distorted.

[0051] ②Aligning scans: Eye tracking or head tracking can help ensure that each scan is in the same spatial position. This is very important for comparing multiple scans and for computer-assisted analysis and localization of lesions. By accurately aligning the scans, doctors can more easily detect any changes or abnormalities.

[0052] ③ Reduce artifacts: Eye tracking or head tracking can also reduce artifacts caused by breathing, heartbeat and other movements. These movements can cause artifacts in MRI images, leading to difficulties in diagnosis and possibly requiring repeated scans.

[0053] In this embodiment, eye tracking or head tracking is performed through the tracking component, which can improve the quality of magnetic resonance imaging images, reduce artifacts, and ensure the stability and consistency of scanning.

[0054] In one embodiment, if Figure 1 as well as Figures 4 to 6As shown, the tracking component includes a first light source (not shown) and a first image sensor 32 located in the Faraday cage 1, the first light source is used to emit infrared light to the eyes of the detection object, and the first image sensor 32 is used to collect photos of the eyes of the detection object.

[0055] When the eyes of the detection object are open, the eye movement and gaze direction of the detection object when viewing a specific virtual visual scene can be monitored based on the eye photos of the detection object collected by the first image sensor 32, and relevant analysis can be performed to achieve eye tracking. In practical applications, the movement of the head of the detection object can be inferred based on the eye photos of the detection object collected by the first image sensor 32 through a certain algorithm to achieve head tracking.

[0056] Since infrared light is invisible light, the first light source emits infrared light to the detection object, which can achieve eye tracking and head tracking without affecting the detection object's viewing of the virtual visual scene provided by the display element 21.

[0057] In one embodiment, if Figure 1 as well as Figures 4 to 6 As shown, the virtual reality presentation component 2 also includes a beam splitter 23 located in the Faraday cage 1, and the beam splitter 23 is located between the display element 21 and the optical path transmission element 22. The virtual visual scene provided by the display element 21 is transmitted through the beam splitter 23 and then transmitted to the eyes of the detection object in the optical path transmission element 22; the first image sensor 32 is located between the first light source and the beam splitter 23, and the infrared light emitted by the first light source is reflected by the beam splitter 23 and then transmitted to the eyes of the detection object in the optical path transmission element 22.

[0058] For example, Figure 1 as well as Figures 4 to 6 As shown, the display element 21 can be directly facing the eyes of the detection object, and the virtual visual scene provided by the display element 21 does not need to change the transmission direction, and is directly transmitted through the spectroscope 23 and then transmitted to the eyes of the detection object in the optical path transmission element 22; the optical path transmission paths between the first light source and the spectroscope 23 and between the first image sensor 32 and the spectroscope 23 are perpendicular to the transmission path of the virtual visual scene provided by the display element 21, and the infrared light emitted by the first light source changes the transmission direction after passing through the spectroscope 23, and then is transmitted to the eyes of the detection object in the optical path transmission element 22. Similarly, the information displayed in the eyes of the detection object is transmitted to the spectroscope 23 through the optical path transmission element 22, and then changes the transmission direction, and then is reflected to the first image sensor 32 through the spectroscope 23, so that the first image sensor 32 can collect the eye photos of the detection object. In this way, the display element 21, the first light source and the first image sensor 32 can share the optical path transmission element 22 for transmission, which can simplify the structure of the immersive virtual reality system.

[0059] In one embodiment, if Figure 3 , Figure 7 and Figure 8 As shown, the display element 21, the optical path transmission element 22, the first light source and the first image sensor 32 correspond to each other one by one and the number is two. For example, the left eye of the detection object can correspond to one display element 21, one optical path transmission element 22, one first light source and one first image sensor 32, and the right eye of the detection object can correspond to another display element 21, another optical path transmission element 22, another first light source and another first image sensor 32.

[0060] The tracking component also includes a motion monitoring camera module 33 disposed between two display elements 21 disposed side by side. The motion monitoring camera module 33 is used to track the position information of the head coil 30 of the detection object, the face of the detection object, and the nose bridge marker of the detection object. The motion monitoring camera module 33 is disposed between the two display elements 21 to avoid interference with the transmission of the virtual visual scenes of the two display elements 21.

[0061] Since the eyes of the detection object need to be open when the first light source and the first image sensor 32 are used for eye tracking and head tracking, when the eyes of the detection object are closed, the first image sensor 32 cannot capture a picture of the eyes, so head tracking and eye tracking cannot be performed. In this embodiment, the motion monitoring camera module 33 can track the position information of the detection object's head coil 30, the detection object's face, and the detection object's nose bridge marker when the detection object's eyes are closed, thereby achieving head tracking.

[0062] It should be noted that the first light source mentioned above may be a light source group including only one minimum light-emitting unit or a light source group including multiple minimum light-emitting units, which is not specifically limited in this embodiment.

[0063] In one embodiment, if Figure 2 As shown, the motion monitoring camera module 33 includes a second light source 331 and a second image sensor 332 located in the Faraday cage 1. The Faraday cage 1 can protect the second light source 331 and the second image sensor 332 from the magnetic field and radio frequency interference in the magnet cavity 20; the second light source 331 is used to emit infrared light to the facial, head and nose bridge markers of the detection object, and the second image sensor 332 is used to collect photos of the face, head and nose bridge of the detection object.

[0064] When the eyes of the detection object are in a closed state, the second light source 331 emits infrared light to the face, head and nose bridge markers of the detection object, and the second image sensor 332 collects photos of the face, head and nose bridge of the detection object, so as to monitor the head movement of the detection object when looking at a specific virtual visual scene, thereby realizing head tracking.

[0065] Since infrared light is invisible light, the second light source 331 emits infrared light to the face, head and nose bridge markers of the detection object, so as to achieve head tracking without affecting the detection object's viewing of the virtual visual scene provided by the display element 21.

[0066] In one embodiment, if Figure 1 and Figure 2 As shown, the immersive virtual reality system also includes a computing processor 4 and an optical fiber 5. The computing processor 4 is located outside the magnet cavity 20, and the computing processor 4 is connected to the tracking component through the optical fiber 5.

[0067] Specifically, the computing processor 4 is connected to the first image sensor 32 and the second image sensor 332 of the tracking component through the optical fiber 5. The head tracking and eye tracking data of the detection object when the eyes are in an open state are calculated based on the eye photos of the detection object collected by the first image sensor 32, and the head tracking data of the detection object when the eyes are in a closed state are calculated based on the photos of the face, head and nose bridge markers of the detection object collected by the second image sensor 332.

[0068] The connection between the computing processor 4 and the tracking component via the optical fiber 5 has at least the following benefits:

[0069] ① High-speed transmission: Compared with traditional copper wire connections, optical fiber 5 has faster transmission speeds and can support greater bandwidth.

[0070] ② Large bandwidth: The optical fiber 5 connection has a large bandwidth and can transmit multiple signals and data streams simultaneously to meet the needs of different users and applications. In this embodiment, the optical fiber 5 simultaneously transmits the data of the first image sensor 32 and the second image sensor 332 of the tracking component.

[0071] ③ High-quality signal: The optical fiber 5 connection has a very strong anti-interference ability, and the signal transmission quality is stable and reliable. It is not affected by electromagnetic interference, lightning and other external electromagnetic radiation. In this embodiment, the tracking component is located in the magnet cavity 20, and the computing processor 4 is located outside the magnet cavity 20. The tracking component and the computing processor 4 are connected by the optical fiber 5, so that the signal transmission is not affected by the electromagnetic and radio frequency interference in the magnet cavity 20, and the signal transmission quality between the tracking component and the computing processor 4 is guaranteed.

[0072] Preferably, the optical fiber 5 is a glass optical fiber 5. As the glass optical fiber 5 has strong anti-interference ability and low sensitivity to electromagnetic interference and noise, it can effectively resist the influence of electromagnetic radiation and external noise, thereby ensuring the reliability of data transmission between the tracking component and the computing processor 4. At the same time, the glass optical fiber 5 is small in size and light in weight, and does not take up too much space.

[0073] The present application also provides a magnetic resonance system, including a scanner, a head coil 30, a Faraday cage 1, a display 21 and an optical path transmission component 22. The scanner surrounds to form a magnet cavity 20; the head coil 30 is arranged in the magnet cavity 20 and has a containing space. When the detection object is subjected to magnetic resonance scanning imaging, the head of the detection object is placed in the containing space of the head coil 30; the Faraday cage 1 is arranged in the magnet cavity 20 and is located at the upper part of the head coil 30; the display 21 is located in the Faraday cage 1 and is used to provide a virtual visual scene; the optical path transmission component 22 is at least partially located outside the Faraday cage 1, and is used to transmit the virtual visual scene of the display 21 to the containing space of the head coil 30. The magnetic resonance system provided in the embodiment of the present application has the immersive virtual reality system for the magnetic resonance system in any of the above embodiments, and therefore has all the beneficial effects of the aforementioned immersive virtual reality system for the magnetic resonance system, which will not be repeated here.

[0074] In actual applications, the magnetic resonance system also includes a correction module. The computing processor 4 of the immersive virtual reality system is electrically connected to the correction module. The correction module obtains the head tracking and eye tracking data when the eyes of the detection object are in an open state and the head tracking data when the eyes of the detection object are in a closed state calculated by the computing processor 4. The correction module can perform eye position correction, line of sight direction correction, head position correction and head posture correction based on the above data, thereby improving the quality of magnetic resonance imaging images, reducing artifacts, and ensuring the stability and consistency of the scan.

[0075] In one embodiment, if Figure 1 , Figure 2 as well as Figures 4 to 6 As shown, a fixing component (not shown) is provided on the head coil 30, and the fixing component is used to fix the side of the optical path transmission component 22 away from the display component 21. In this way, not only can the end of the optical path transmission component 22 away from the display component 21 be prevented from being suspended in the air, but also the side of the optical path transmission component 22 away from the display component 21 can be aligned with the eyes of the detection object through the fixing component, so that the eyes of the detection object can watch the virtual visual scene provided by the display component 21, and the smooth progress of eye tracking and head tracking can be ensured.

[0076] In actual applications, the fixing component can fix the side of the optical path transmission component 22 away from the display component 21 to the head coil 30 in a manner commonly used in the prior art. For example, in one embodiment, the fixing component includes a first clamping component and a second clamping component, and the side of the optical path transmission component 22 away from the display component 21 is fixed to the head coil 30 by the first clamping component and the second clamping component. This embodiment does not make any specific limitations on this.

[0077] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
